Major defect such as existing temperature sensor is as follows：
1st, housing easily comes off：Housing is two kinds of different materials with epoxy resin, and its coefficient of expansion is different, therefore, during production
Both one has been linked to be at ambient temperature.Specify in temperature sensor industry standard, the temperature sensor of Xin Ru factories is produced
Product, its resistance to pulling force standard can be the pulling force of resistance to 20N, but constantly experience cold and hot change in use, and its housing will come off；
2nd, water inlet failure：Epoxy resin is also two kinds of different materials from the insulant PVC of cable, in multiple cold and hot change
Under, its epoxy resin also occurs gap with PVC material, causes steam to enter into pad, causes failure.Temperature to Xin Ru factories
Degree product sensor, will be soaked using 100 DEG C of boiling water, specify in industry standard, and immersion is not failed for 400 hours.It is real
On border, many temperature sensor products do not reach the index of standard requirement.
The content of the invention
The problems referred to above that the present invention is present for solution prior art, there is provided a kind of sensor and preparation method thereof, sensor
Insulating protective layer it is difficult for drop-off, resistance to pulling force is difficult up to 200N, in sensor into water, is soaked in 100 DEG C of boiling water
Will not fail within 4000 hours, improve service life, processing and fabricating is simple, production efficiency is high.
The purpose of the present invention is achieved through the following technical solutions：
A kind of sensor, including the insulating protective layer of the conductor and outside cladding of sensing element and sensing element connection, its feature
It is that the conductor is two conductive films in one section of FPC conductive strips, the outer layer of the FPC conductive strips is insulation film, institute
The one end for stating two conductive films is welded as a whole with the sensing element respectively, and the insulating protective layer is the sensing element
The integrative-structure being extruded into by entirety PVC with the FPC conductive strips.
Improvement to above-mentioned technical proposal：One section of Jing quadric injection mould PVC comprising the sensing element outside the insulating protective layer
Insulating barrier forms the sensor probe of integrally closed.
Further improvement to above-mentioned technical proposal：The sensing element is critesistor.
Further improvement to above-mentioned technical proposal：Described insulation film is PVC insulant.
A kind of manufacture method of the sensor, it is characterised in that comprise the steps：

Further improvement to above-mentioned technical proposal：The sensing element is critesistor.
Improvement to above-mentioned technical proposal：The insulation film of the FPC conductive strips is PVC insulant.
Advantages of the present invention and good effect are：
The conductor of sensing element of the present invention connection is two conductive films in one section of FPC conductive strips, the one of two conductive films
End is welded as a whole with sensing element respectively, and the insulating protective layer for adopting is that sensing element and FPC conductive strips are squeezed by entirety PVC
Go out the integrative-structure to be formed.So, without using epoxy sealing, but use same insulant（PVC）By two
Conductive film and sensing element are encapsulated into inside insulating protective layer using integral extrusion and quadric injection mould mode.Due to using
Same insulant（PVC）, difficult for drop-off or separation, the housing for completely solving existing temperature sensor easily come off and shell
The problem of water inlet failure in vivo.Its resistance to pulling force can bring up to 200N, and the resistant to boiling water time can be mentioned 4000 hours, compare mesh
Front industry standard improves 10 times, improves the service life of product.
Comprising two conductive thins being parallel to each other inside the FPC conductive strips of the manufacture method processing and fabricating of inventive sensor
Film, each bar conductive film are discontinuously arranged along its length, so can be with the very long FPC conductive strips of Continuous maching, then, according to setting
The position that the length that meter is required conductive film described in FPC conductive strips disconnects is cut, and forms some short FPC conductive strips.
So processing method is simple, is easy to mechanization, automated production, production efficiency to increase substantially, and reduces artificial operation, subtracts
Light work intensity, reduces cost of manufacture.
